IMPROVEMENT IN ADJUSTABLE STOVE-BACKS.

Specification forming part of Letters Patent No. 222,183, dated December 2, 1879; application filed September 9, 1878.

To allwhom it may concern:

Be it known that I, PRIoE H. FELLows, of

the city of Kokomo, county of Howard, and

State of Indiana, have invented certain new and useful Improvements in Adjustable Stove- .Backs, of which the following is a specificasimilar parts.

Figurel is a front view of my improved stove-back. Fig. 2 is a rear view thereof. In each of these two views one-of the end pieces, 13, is shown apart from the central piece A. Fig.3 is a transverse verticalsection on the dotted line as as, showing the two parts A and B connected together by the dovetail ribs 1) b and the corresponding grooves an, as when Fig. 4 is a view similar to that shown apart from each other, and giving an end view of the enlargement of the part A.

In said drawings, the portion marked A is the main part of the stove-back, and is constructed short enough to enter the smallest stoves usually made, in which this pattern of back is used. B B are removable ends, by

I which the length of the back is increased so that it shall fit larger stoves.

The part A has grooves a aformed to fit the dovetail ribs 1) b on the part B. The ribs by 21 enter the grooves a a and slide along them until the required adjustment is had. This forms an exceedingly simple and secure way of connecting the several parts of a stove-back without injuring their utility by holes or slots extending entirely through the metal, as the two dovetailed ribs and grooves together form all the fastening necessary, which one alone will not do.

The collinectingdovetails may, of course, be reversed as to the parts upon which they are located; but I prefer the position shown, as

it is better protected from the action of the flames.

The bottom edge of the part A is reduced in thickness upon one side and the corresponding; edges of the parts B Bupon the other side, so that the aggregate thickness ofthe I This back can thus be inserted in place of the worn-out ordinary back, and its lower edge will enter the same groovewithout its being changed.

The thickness of the part A is increased in the center to about equal that of both the parts elsewhere. This additional metal, being back much more durable, as it will thus withstand the action of the flame much longer and at but comparatively little expense. shape it is about as serviceable as one having the extra thickness throughout its entire length.

or more rows of hollows or depressions by which the strength of the metal is there lessened, and pieces are thereby moreeasily broken off should it become necessary to reduce the Width of the back.

By the use of my invention the backs of stoves already in use that have been burned and but little trouble in securin g a perfect fit, the capacity of adjustment being such that a single pattern of backwill fit nearly all sizes of stoves made.

by Letters Patent, is

1. The combination of two or more plates, constructed substantially as described, one or into each other, and forming an adjustable the uses and purposes specified.

plates B B, having dovetailed ribs 1), substantially as herein shown and specified;

Having thus fully described my said invention, What I claim as new, and desire to secure more of which shall each have two or more, dovetailed ribs, and theother or others corresponding dovetailed grooves, sliding endwise stove-back, sul'JstantiaIIy as shown, and for 2.
